An LED tube light having a substantially uniform exterior diameter from end to end is disclosed. It has a glass light tube with narrowly curved end regions at ends for engaging with end caps, in which outer diameter of each end cap is equal to outer diameter of light tube. LED tube light also include a thermal conductive ring. The narrowly curved end region is formed by glass tempering. End caps are joined to the light tube by sleeving over the rear end regions with a hot melt adhesive disposed between the rear end region, the transition region, the insulating tubular part and the thermal conductive ring. An outer diameter of thermal conductive ring is the same as the outer diameter of the main region of the light tube. The transition region is curved, and an outer diameter of rear end region is less than that of the main region. |
